Intended Use and Function in the Vehicle

The presented set belongs to the Parking Sensors category and is intended for installation in the front part of the body. The sensors work with the factory PDC system, responsible for precise detection of obstacles in front of the vehicle when maneuvering in parking lots, narrow streets, or when approaching a garage wall.

A set of four elements allows for a consistent replacement of the entire row of sensors in the bumper, which is particularly beneficial when several of them show signs of wear or unstable operation. This ensures uniform system sensitivity and predictable operation of the parking assistant.

Color Scheme and Visual Matching

The Stannite Grey Metallic - 786 color has been chosen to match Mercedes' factory paint palette, which helps to minimize shade differences between the sensor and the bumper paint. This is important both aesthetically and practically – the element does not require additional painting if the bumper is the same color.

The neutral, metallic shade also blends well with other shades of grey and dark body colors, making the sensors visually discreet while maintaining the factory finish character.

Application in Mercedes W204 and W212 Models

The set has been prepared for Mercedes C-Class W204 generation and E-Class W212 generation vehicles equipped with the front PDC system. This provides the user with a set of components structurally matched to the factory mounting sockets in the bumper, facilitating service work and reducing replacement time.

In practice, this means the ability to:

• restore the full functionality of the front parking system after the failure of one or more sensors,
• replace worn-out elements with a set of uniform color finish,
• restore correct operation with the factory PDC controller without the need for installation modifications.

Set Characteristics and Installation Benefits

A set of four sensors allows for a consistent replacement in the entire front parking zone, minimizing the risk of sensitivity differences between individual measurement points. This is particularly important in vehicles where the PDC system operates continuously and is an important support during daily use.

Key benefits of the set include:

• maintaining the original appearance of the bumper thanks to the matching color,
• easier installation due to being designed for a specific vehicle zone (front),
• the ability to restore the correct operation of the parking system's acoustic and visual signaling.

Selection, Installation, and Practical Tips

When selecting parking sensors for a Mercedes, it is crucial to pay attention to compatibility with the specific vehicle generation and the PDC system used in the car. If in doubt, it is advisable to use manufacturer markings or vehicle data to confirm the set's compatibility with the given configuration.

During installation, it is recommended to:

• check the condition of the electrical harness and bumper sockets,
• ensure the sensors are securely seated in their holders to avoid play and incorrect readings,
• after completion of work – perform a PDC system test, preferably in controlled conditions (e.g., against a wall or post).
